 \hline\hline \end{tabular*} {\centering \caption*{\begin{footnotesize} \textit{Notes:} This table checks robustness of our baseline event study estimates in Table \ref{tab:es1} by changing covariates or how control areas are defined. Columns 1-3 report estimates for MSCZ pairs, while Columns 4-6 have results for BC pairs. Columns 1 and 4 (2 and 5) require controls areas to have no state minimum wage increases 2 (4) years prior, instead of the baseline 3. Columns 3 and 6 change the dependent variable from log employment \textit{rate} to log employment. They also add controls for log population, and log employment and log earnings in non-restaurant sectors. This is similar to JNR's TWFE specification. However, keeping in line with the specification in the baseline event-study equation \ref{eq:ES}, our controls are also in differenced form. Outcomes, such as MWE and OWE are defined similarly as Table \ref{tab:es1}. Standard errors, reported in parentheses, are clustered at the state level. Stars indicate statistical significance as follows: \sym{*} \(p<0.10\), \sym{**} \(p<0.05\), \sym{***} \(p<0.01\) \end{footnotesize}}} \end{table}
